5DescriptionCVE.org
A flaw has been found in GPAC up to f1219cde. Affected by this issue is the function gf_list_count of the file utils/list.c of the component MP4Box. Executing a manipulation can lead to use after free. The attack is restricted to local execution. The exploit has been published and may be used. Upgrading to version abi-16.23 can resolve this issue. This patch is called 49dee5cad329cfed310c1682703df7daa47df31a. It is suggested to upgrade the affected component.
AnalysisAI
Use-after-free in GPAC's MP4Box multimedia tool (all versions through commit f1219cde) allows a local low-privileged attacker to corrupt heap memory via the gf_list_count function in utils/list.c, resulting in application crashes and potentially limited code execution within the process. The fix released in abi-16.23 (commit 49dee5cad329) addresses multiple interrelated UAF and null-dereference conditions across the scenegraph manager, BIFS memory decoder, and AV1 reframer subsystems. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local shell access to the target system with at minimum low-privilege credentials (consistent with PR:L in the CVSS 4.0 vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 4.8 with vector AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P accurately characterizes limited real-world risk: exploitation is strictly local, requires only standard user credentials, and the demonstrated impact is bounded to low confidentiality, integrity, and availability effects within the GPAC process. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade GPAC to version abi-16.23 or later, which incorporates patch commit 49dee5cad329cfed310c1682703df7daa47df31a. … Detailed patch versions, workarounds, and compensating controls in full report. |
